I'm sure there is such a topic on the forum, but after scrolling through the search, I didn't find anything. The bottom line is that I want to enable compilation of C sources in DUB and then build the project with the connection of libraries. I would like to see an example of such a dub.json project.

Enable libraries (flags) -lm, -lX11, -lXrandr.

{
	"name" : "test",
	"description" : "Test project",
	"dependencies" : {
	}
}

It turns out to compile everything manually, but I would like to do it all through the dub project.

.
├── dub.json
└── src
    ├── app.d
    └── main.c

I remember a long time ago, when I first started learning D, I set up a project in dub.json so that he compiled the sources written in C, linked the necessary libraries and then assembled the project in D along with the C object files. How to do it now - I have already forgotten.

Does anyone have examples of such a configuration?

I managed to do it like this:

{
    "name": "app",
    "authors": [
        "Alexander Zhirov"
    ],
    "description": "MyProgram",
    "dflags": [
        "-i"

    "libs": [
        "pq"

    ],
    "sourceFiles": [

    ]
}

It would be nice if dub included a directory of example configurations for common issues like this.

It has an example directory: https://github.com/dlang/dub/tree/master/examples

If your configuration is missing, you could make a Pull Request to add it.

So it does. Thanks.

We might also link to that on the dub.pm website.

And if there are two compilers in the system - dmd and ldc, which compiler chooses dub.json? And how do I specify the specific compiler I want?

Following the command line documentation [1], you can use the --compiler option to select which to use. You can make the dub.json do different things depending on the target and/or compiler, but the default works fine regardless if you're doing something simple.
